How your personal information is managed
The Ministry of Health has consulted with the Privacy Commissioner to ensure NZ COVID Tracer protects your privacy.
The personal information and contact details you choose to register through NZ COVID Tracer (on the ‘register your details’ and ‘let us know where you are staying’ screens) are provided to the Ministry of Health so contact tracers can quickly get in touch if you are identified as a close contact of someone who has COVID-19.
Any further information you decide to record through NZ COVID Tracer – for example, the QR codes you scan, your manual diary entries or your NHI number - is stored securely on your phone. Digital diary entries are automatically deleted after 60 days.
The contact alert process for NZ COVID Tracer does not involve transmitting any information from your phone. If you are identified as a confirmed or probable case of COVID-19,
it is your choice whether to share your digital diary with the Ministry. You are in control of your data.
Any information (excluding anonymous statistical information) you provide to the Ministry will not be shared with other government agencies except where the agency is directly involved in the public health response and sharing the information is necessary for public health purposes during the COVID-19 pandemic.
It will never be used for enforcement purposes.
If any information you provide to the Ministry is added to your health record, for example if you test positive for COVID-19, it will be kept for the same duration as the rest of your health record.
The Office of the Privacy Commissioner has been consulted and is satisfied that the privacy implications (and their mitigations) for the current release of NZ COVID Tracer have been appropriately recorded in the Privacy Impact Assessment available below.
